Specification of Letters Patent.

Patented June 9, 1914.

Application filed January 28, 1913. Serial No. 744,747.

1 '0 all whom it may can earn Be it known that I, LOUIS Orr, a citizenof the United States. residing at Harrisburg, in the county of Dauphinand State of Pennsylvania, have invented certain new and usefulImprovements in Gas-Lighters, of which the following is a.specification, reference being had to accompanying drawings.

This invention relates to gas lighters and more particularly to a pilotlight designed to be used in connection with as stoves or ranges. V

The principal object of the invention is the provision of a gas lightercomprising a pilot light adapted to burn continuously, the flame thereofbeing adapted to be in creased in size when the pilot tube is moved intoclose proximity to the stove burners.

Another object of the invention is the provision ofawhousing suitablysupported upon the stove frame between the burners thereof and providedwith a rotary plug which. has secured to the upper end thereof a pilottube, means for admitting gas to the pilot tube through the rotary plugand means for admitting additional gas thereto to increase the size ofthe pilot light when the latter is moved into close proximity t the gasburners.

Another object of the invention is the provision of a gas lighter of theabove stated character which is provided with means for regulating thesize of the pilot light.

A still further object of the invention is the provision of a gaslighter of the above stated character provided with means forcontrolling the gassupply to increase the size of the light.

A still further object of the invention is the provision of a gaslighter provided with a rotary pilot tube and hand operable meansconnected to the pilot tube whereby the latte may be moved into closeproximity to the s burner it Aastillifurtlierobject of the invention isthe provision ofja gas lighter of the above stated haracter" including apilot tube, the end .0 s Nh-ich its-{provided with. a shieldarranged-thelow the orifice in the end thereof adapted towprevent'the'pilot lightfrom being puffedeout upon the lighting of the gasburners of the stove.

With these and other objects in View as will appear as the descriptionproceeds, the invention comprises the various novel features ofconstruction, combination and arrangement of parts as will be more fullydescribed hereinafter and set forth with particularity in the appendedclaims.

Referring to the drawings, Figure 1 represents a top plan view of a gasstove with my improved gas lighter attached thereto; Fig. 2 is a sectiontaken on the line 22 of Fig. 1. Fig. 3 is a vertical longitudinalsectional view through the rotary valve and the housing therefor; Fig. 1is a horizontal section taken on the line 41 of Fig. 3; Fig. 5.is avertical transverse section taken on the line 5-5 of Fig. 3; Fig. 6 is avertical section taken on the end of the pilot tube and the shieldsecured thereto.

Similar characters of reference are used to denote like parts throughoutthe accompanying drawings and the annexed specification.

Referring more particularly to the drawings the reference character 1indicates a gas stove which may be of any desired shape or design and isprovided with the usual burners 2 which are disposed below the top plate3 and are separately connected by means of gas pipes 4 to the main gassupply pipe 5 disposed at one side of the stove.

My improved gas lighter is shown to consist of a housing 6 which ismounted upon a supporting bar 7 and is securely held thereon through themedium of bolts 8. This bar, in this instance, is shown as arrangedtransversely of the stove, and is supported by rods 9 that extendlongitudinally of the stove and are suitably secured to the oppositeends thereof. The bar 7 is secured to the supporting rods '9 throughthemedium of angularly shaped clamps 10 which are securely clamped overthe supporting rods 9 and to the bar 7 by bolts 11. The housing 6 isprovided at one end thereof with a vertically extending tapered bore 12in which is revolubly mounted a tapered plug 13, securely held thereinfor free rotation through the medium of washers 14 and a screw 15threadedly connected to the lower end of the plug 13. The upper end ofthe tapered plug 13 is provided with a crown gear 16 thatmeshes with apinion 17 secured to the inner end of an operating shaft 18, the forwardend of which is journaled in a suitable supporting bracket 19 formedupon the base flange of the housing 6, and the other end is journald ina bracket 20 formed at the end of the bar 7 The outer end of theoperating shaft 18 is provided with a suitable hand wheel 21 whereby theplug 13 may be revolved through the-medium of the crown gear 16 and thepinion 17 connected thereto and to the operating shaft 18. The upper endof the plug 13 is formed toprovide a horizontally extending arm 22 whichis threaded at the end to receive the threaded end of a pilot tube 23,-the outer end of 'which, as shown in Fig. 6, is provided with a reducedorifice 24 where a pilot light of the desired size-i adapted to burncontinuously.

A shield is secured to the lower portion of the .pilot tube 23 beneaththe orifice 24 so as to prevent the ilot light from being puffed outupon the lighting of the gas, stove burners. When the pilot tube restsin its normal position the pilot light burns above the shield 25, butwhen the pilot tube is moved into close proximity to the gas stove withan orifice 26 opening throu h the.up-

burners the pilot light is automatically in creased in size so as toproject forwardly beyond the end of the shield 25 so as to readily andquickly light the burners. The pilot light will decrease to its normalsize when the, pilot tube has again moved to its normal or inoperativeposition.

' The tapered plug 13 is provided centra'lly per end of the plug and isclosed y a screw plug 27. The lower end of the orifice 26 communicateswith an annular groove 28 formed in the outer face of the plug 13through the medium of a horizontally extending passage way 29. The plug13 has a pair of vertical semi-annular grooves 30 formed thereinarranged below and in spaced relation to the annular groove 28.

These grooves 30 are connected to theannular groove 28 .by verticallyextending inclined grooves 31. The arm 22 of the plug 13 is providedwith a horizontally extending passage way 32 which communicates with thecentral orifice 26, thus establishing communication between the pilottube 23 and the annular groove 28.

The housing 6 is provided at the upper portion thereof with ahorizontally extending extension 33 which has formed 'therein afhorizontally extending passage way 34,-thepassage way at one endcommunicating with the tapered bore 12 andthe annular groove 28 of theplug 13, the'other-end of the pas sage way being closed bya screw plug35. The extension 33 is provided below and in spaced relation to thepassage way 34 with a secondary p'assage way 36 which is en larged andinternally-threaded, as shown at 37-, at the outer endthereof for thereception of the gas supplypipe 38. The other cause the end of thepassage way 36 communicates with the bore 12 of the housing 6 and withthe partial semi-annular grooves 30 of the plug 13 when the latter isrotated to an operative position. The passage way 36 is providedintermediate its ends with a transversely extending controlling valve 39which is shown to be in the form of a tapered plug provided with atransverse opening 40 whereby the gas may be allowed to pass 1 throughthe passage way 36 into the grooves 30. This controlling valve 39 isdesigned to regulate the .admission of gas to the grooves 30, wherebythe increased size of the pilot light may be varied at will. Theextension 33 is also provided with a-vertically extending opening 41which extends from the top of the extension 33- down through the passageway34 where it is reduced in size to form a valve seat 42-and a passageway 43 establishing communication between the passage way' 34 and thepassage way 36. A plug 44 having the lower end thereof tapered isthreaded into the opening 41 and adapted to be screwed down so that thelower end thereof may be disposed relative to. the. seat 42 to regulatethe passage of the gas from the inlet pipe 38 through the passage way 34to the annular groove 28. In other words the plug serves as a meansforincreasing ofdecreasing the size of the pilot light.-

In the operation of the device, the parts being arranged in the positionshown in Fig. 3, the pilot light burns at the orifice 24 continuously.When it is desired to light the various-burners-of the gas stove-theoperating handle or wheel 21 is revolved to impart a similar motion tothe pilot tube .23, and in so doing the partial semi-annular grooves 30are moved into communication with the passageway 36 whereby anadditional supply of gas will be admitted to the annular groove28, thusincreasing the size of the pilot light so that the latter extendsforwardly and beyond the end of the shield 25 whereby the gas burnersmay be readily and quickly lighted. After the burners have been lightedthe pilot tube is again moved to its normal or inoperative position, the

partial semi-annular ooves 30 being moved out of engagement'wlth thepassage way 36 at the same time whereby the supply of 'gas to the pilottube will be diminished so as to From the foregoing description taken-inconnection with the accompanying drawin the advantages of constructionand t e pilot light to decrease to its normal.

method of operation will be readily-a p ar-' cut to those skilled in theart to 'which t e in vention relates, and while I have described theprinciple of operation of the invention,
